Meethi asked a question

Subject: Chemistry, asked on on 25/9/16

In Ma2b2c2 type pls draw all geometrical, optical and stereoisomers. Actually I'm confused that if we change the order of a, b c in the compound then a new geometry is formed and that will also behave different to plane polarized light. So for this case we can arrange in 5 different orders of a2b2c2. So are all 5 optical isomers? And then if we take their mirror images then we'll Have 10 optical isomers as all 10 have diff rotation. So what is geometrical isomerism here?
